Well, if your main job doesn't fit with your need you always can find side projects, go to meetups, learning some new language, or framework.
Other question is to talk with your boss/manager and tell him some things to implement, like internal talks, coding kata, technical meetings or something.
It's not posible try to develop side project, contribute to open source in GitHub or talk with other people and try to find some new projects.
Follow different blogs, discuss here in hashnode, and try to learn all of things you want or are interested in.
